The Human Cyber Physical System (HCPS) in Manufacturing 4.0 represents the integration of human intelligence with cyber-physical systems to create smarter, more efficient production processes. This synergy enhances decision-making, real-time monitoring, and adaptability in manufacturing environments. However, the current implementation and research on HCPS are still limited, particularly when applied to Supervisory Control and Data Acquisition (SCADA)-based manufacturing. When searching the Scopus database, during the last 10 years there were only 7 conference proceedings, 6 journals and 3 book series. The aim is to provide the application of HCPS in SCADA-based manufacturing and provide an overview of the architecture of both SCADA and HCPS when applied to real-world systems. The SCADA software AVEVA InTouch HMI, utilized in combination with Schneider Electric's Programmable Logic Controller (PLCs) hardware, was employed to develop a SCADA-based manufacturing system. This research resulted in a prototype HCPS for predictive maintenance of water-cooling systems. The system successfully reduced potential downtime to zero hours. Additionally, it effectively prevented unplanned machine breakdowns.
